Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an apparatus for simultaneously and continuously producing oxygen gas and hydrogen gas in a state in which they can be mixed or separated from each other from the same machine.

It is well known that there are a number of devices that produce oxygen or hydrogen separately and independently from each other, and the present invention also facilitates the above-mentioned separate production, but the main purpose of this invention is rather to The idea is to find many benefits in being able to generate an oxyhydrogen mixed gas at the same time.

This is because hydrogen and oxygen react with each other to produce water at room temperature, but when this reaction is accelerated by an electric spark or a platinum catalyst, an exothermic reaction occurs with explosive intensity, for example at 25°C. at 1 atm
It produces heat of 68.313Kcal/mol, and the temperature at that time is
Since it can reach up to 2800℃, it is not only useful as an oxyhydrogen torch for heat treatment processes such as welding and cutting steel plates or deforming glass, but it can also be easily used as a direct heat source or light source. It is.

Welding using a mixed gas of oxygen and hydrogen (hereinafter referred to as oxyhydrogen welding) has the following points compared to other welding methods, such as acetylene oxygen gas welding, arc welding, or electric resistance welding. Since it reduces oxidation and nitridation phenomena that occur during processing, phase changes or transformations in mechanical properties that occur from overlaying, cutting, etc. when welding easily oxidized metals, light alloys, nickel chrome steel, etc. are small; and
It is said to be advantageous in that the original strength or hardness can be maintained without any reduction.

(b) Prior art However, in conventional oxyhydrogen welding, for example, high-pressure oxygen gas and hydrogen gas, which are separately compressed and filled into a thick-walled seamless steel cylinder-type container called a cylinder, are For example, since the cylinders were mixed at a ratio of 1:4, the cylinders were heavy and had poor maneuverability and portability, as well as strict regulations to prevent the many dangers that arise when handling high-pressure gas. It is well known that there exists

Therefore, if a device capable of easily and continuously supplying an oxyhydrogen mixed gas under normal pressure is developed, the above-mentioned concerns during oxyhydrogen welding, etc. will be eliminated at once.

Conventionally known oxyhydrogen mixed gas generation means include the following electrolysis method, whose basic structure and operation are as follows: An electrolytic solution with the minimum electrical resistance value, for example, 20%
When a pair of electrodes is placed in a large solution of 30% sodium hydroxide (NaOH) or 30% caustic potash (KOH) and a direct current is passed between the electrodes,
The cations in the aqueous solution that have become ionic conductors move toward the cathode, and the anions move toward the anode. Along with this, a chemical reaction occurs at the interface between the electrode and the ionic conductor, and oxygen (O _{2 )} is removed from the anode. ), hydrogen (H ₂ ) is generated as bubbles from the cathode at a ratio of 1:2.

Faraday's law holds between the amount of bubbles generated and the amount of electricity, and the two are proportional to each other, so
If a large number of bubble groups are expected to be generated, a correspondingly large amount of electric field energy is required.

However, the bubbles generated on the electrode plate surface are uniformly small particles, and the buoyancy of the bubbles themselves is not enough to float away from the plate surface, and the group of small bubbles reaches a total buoyancy of more than a certain value. In particular, when a large number of electrode plates are placed closely together, the levitation of gas bubbles tends to be uneven. This is extremely inconvenient when a fixed quantity supply is required, and there is also the concern that the bubbles adhering to the surface of the electrode plate act as an insulating layer, lowering the electrical conductivity and slowing down electrolytic production.

One way to solve the above-mentioned problems is to constantly set the electric field energy too high to increase the ability to generate bubbles, but this would cause the problem of continuously consuming a large amount of power over a long period of time. It was hot.

(c) Problems to be Solved by the Invention The first object of the invention is to eliminate the above-mentioned disadvantages, and to quickly separate and float even small bubbles with insufficient buoyancy from the electrode plate surface. An object of the present invention is to create and provide an oxyhydrogen gas simultaneous generator that enables continuous quantitative supply of oxyhydrogen gas, maintains good conductivity, and effectively utilizes electric field energy at all times.

The second object of this invention is to reduce the supply of electric power consumed as electric field energy to the necessary minimum, and to achieve an economical system in which the amount of water consumed is as small as 1/1800 of the generated gas. The purpose of this invention is to create and provide an oxyhydrogen gas simultaneous generator.

The third object of this invention is to create an oxyhydrogen gas simultaneous generation machine that is easy to handle and move, and is safe, without using conventional high-pressure cylinders when generating a mixed gas of oxygen and hydrogen. The goal is to provide the following information.

A fourth object of the present invention is to create and provide an oxyhydrogen gas simultaneous generator that can easily extract oxygen gas and hydrogen gas in a mixed state or in a mutually separated state.

The fifth object of this invention is to provide an apparatus that can generate safe and stable para-hydrogen, which is less flammable, whereas the hydrogen produced by conventional methods is highly flammable and dangerous ortho-hydrogen. It's about getting.

The sixth object of the present invention is to obtain an oxyhydrogen co-generator that does not cause pollution because it returns to water when burned.

A seventh object of the present invention is that it can be used for welding and cutting under normal pressure, negative pressure, or underwater environments, can be used as fuel for general and vehicles, and can be used for glass work, The object of the present invention is to obtain an oxyhydrogen simultaneous generator that can be used for optical fiber processing and semiconductor processing, and can also be useful for air purification.

(d) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides at least one pair of positive and negative electrode plates facing each other in a water tank having a gas outlet hole on the upper surface. By arranging at least a pair of magnetic materials with their polarities facing in the same direction so that the force is directed upward according to Fleming's three-fingered rule in relation to the direction of the potential difference generated between the electrode plates, the acid It simultaneously generates hydrogen mixed gas.

Separating and extracting oxygen and hydrogen can be achieved by interposing a diaphragm between a pair of electrode plates and providing a separate extraction hole.

First, in FIG. 1, a tank 4 is filled with an electrolytic aqueous solution 8 having a small electric resistance value through a water injection hole 6, and an anode 10 and a cathode 1 are placed in the aqueous solution.
A pair of electrode plates consisting of 2 are also provided.

Therefore, when a DC current is passed between the electrodes from the DC power supply 14 outside the tank, a potential difference is generated between the two electrodes, and an electric field in the direction of the arrow 16 is formed, and the aqueous solution 8 becomes an ionic conductor, and the positive ions in the solution Ion is cathode 1
2, anions move toward the anode 10, and oxygen bubbles are generated from the anode 10 interface and hydrogen bubbles are generated from the cathode 12 interface at a ratio of 1:2.

The above-mentioned structure and operation are equivalent to the conventional means for generating oxyhydrogen by water electrolysis, and the present invention improves the deficiencies of the above-mentioned means.

In other words, the oxygen and hydrogen bubbles generated at the interface between the poles and the ionic conductor are initially so small that they cannot separate from the pole surface on their own using only their own buoyancy. Therefore, these small bubbles adhere densely to each pole surface, and the attached small bubbles act as an insulating layer that blocks the electric field 16, deteriorating the bubble generation ability at the interface.
This does not guarantee constant constant supply of oxyhydrogen gas.

Therefore, in the present invention, the electric field 16 is directed in a direction according to Fleming's left hand three finger rule, that is,
In FIG. 1, if a pair of strong magnetic bodies 20 and 22 are installed in order to set the magnetic field 18 that goes from left to right orthogonal to the electric field 16 that goes from the front to the front, Fleming's three-finger rule on the left hand is satisfied. Therefore, an upward force F is generated.

(e) Effect The small bubbles, which had until now been forced to adhere to the electrode surface due to lack of buoyancy, are subjected to the above force F and are moved at high speed in a direction perpendicular to both the electric field 16 and the magnetic field 18, that is, upward. Drifting is allowed.

In other words, each bubble can break off the adhesion force from the electrode surface by adding the drift force to its own buoyant force, and can float toward the water surface.

It seems that this floating movement due to drift is uniformly observed in both oxygen gas and hydrogen gas, but the following assumption seems to hold especially true for hydrogen gas.

As is well known, hydrogen has two atomic nuclei that rotate (spin) per molecule, and those whose spin directions are in the same direction are called ortho-hydrogen.
Hydrogen in opposite directions is called para-hydrogen, and at room temperature or above, it exists in a ratio of 3 ortho to 1 para, but when the hydrogen molecules are ortho, there is a repulsion between the nuclei and it becomes unstable. It is said that under the para state, an attractive force acts between the atomic nuclei, resulting in a stable or activated state, and by using a magnetic material as a catalyst, unstable ortho-hydrogen is converted to stable para-hydrogen. It is said that this is possible.

Therefore, in the present invention, the electric field 16 and the magnetic field 18
If a hydrogen molecule is placed perpendicular to F, and assuming that the direction of force F is opposite to the direction of rotation of ortho-hydrogen, the ortho-hydrogen will be converted to para-hydrogen, and the force F If it is assumed that the direction of is the same as the rotation direction of para-hydrogen, it is estimated that para-hydrogen will further accelerate and rise to the surface.

In this way, when the floating movement of the bubbles is achieved quickly and without interruption, the bubbles remaining on the electrode surface are constantly wiped out, and each electrode surface reuses the aqueous solution as an ionic conductor for the progress of the electrode reaction. Therefore, the electrolytic effect is significantly promoted, and efficient bubble generation can be achieved even with small electric field energy.

(f) Embodiment A specific embodiment of the present invention will be described in detail below with reference to FIGS. 2 and 3.

The rectangular tank 4 has a lid 5, and the lid is provided with a water injection hole 6 with a screw stopper 7 and a gas outlet hole 9, and the tank 4 is filled with an electrolytic aqueous solution 8.

Side frames 23 are installed at the left and right ends of the bottom of the tank.
Terminal bars 25 and 26 are installed between the upper and lower parts of each frame, respectively, and the upper terminal bar 25 has spacers 27 and 24 arranged at equal intervals.
Upper electrode plates (for example, anodes 10) made of non-magnetic material are arranged in a row via 27a, 27b, etc., and spacers 28, 28a, 28b are also arranged at equal intervals on the lower terminal bar 26.
... through the lower electrode plate of non-magnetic material (for example, the cathode 1
2) are arranged in a row and the two electrode plates are interlocked alternately at equal intervals and in a non-contact state, the pairs of positive and negative electrode plates are arranged so that a potential difference occurs in the same direction. Common electric field (see Figure 1, 16)
is formed.

On the other hand, annular permanent magnets 2 with polarity in the same direction are placed on the front side and the opposite side of this laminated electrode plate, respectively.
2 and 20, a magnetic field (see FIG. 18) is created perpendicular to the electric field. 29
and 30 are mounting bolts for fixing the magnet to the side frame.

When the device of the present invention is used for oxyhydrogen welding or cutting, for example, as shown in FIG. When ignited, an oxyhydrogen mixed gas flame 33 is blown out from the nozzle, so it can be used immediately.

In order to separate and take out the oxygen gas generated at the same time, as is well known, a diaphragm (not shown) is interposed between the negative and positive electrode plates, and oxygen and hydrogen are taken out separately from the lid surface. This is easily possible by providing holes (not shown) in each case.

Both gases separated and taken out are suitable to be used individually, but it is also easy to mix them together and use them again.

It is also easy to provide a means for alternately switching between mixed take-out and separate take-out so that they can be selectively used as required.

As a safety measure, for example, in order to be fully prepared for any emergency, we have installed flowmeters, safety valves, and flashback prevention means (not shown) in various parts of the equipment, and when the power is turned off, an automatic discharge device is activated to prevent outdoor use. It is provided with a means for being discharged to.

Not only does it help to float away from 0 and 12, ensuring a continuous and stable supply of oxyhydrogen gas, but also the residual adhesion of small bubbles on the electrode plate surface acts as an insulator and improves conductive performance. The present invention eliminates the adverse effects that had been causing the decline, and it has become possible to maintain the electrical conductivity on the plate surface in the best condition at all times and to effectively utilize the electric field energy.

The second effect of this invention is related to the first effect, because it is possible to avoid constantly supplying excessive electric field energy as in the conventional case, and it is now sufficient to supply the minimum amount of power necessary to form an electric field. , running costs are low.
